Toa'z'z @1523; a a a aa Be it known that I; HA vs NIELsEN, a subject of the King of Denmark, residing at Chicago,-in;-the-.county of Cook and State of Illinois, have invented certain new and useful Improvements in Fan Attachments for Rocking' Cli airsfof which the following is a specification. 7

This invention:v relates to improvementsin fan attachments forrocking chairs and its object is to provide a simple and inexpensive mechanism whlch can readily be attached to a rocking chair and automatically operated by the motion ofthe chair when .the same is in use.

a front view of the attachment. Fig. 3 is a side view of the lower portion of the device. Fig. 4 is an enlarged perspective view of the pawl. Fig. 5 is an enlarged view of the upper portion of the device with one side of the housing removed. Fig. 6 is a plan of Fig. 5 with the housing in section.

Fig. 7 is a view of one of the gear shafts employed. i

' Like reference characters indicate corresponding parts throughout the several views. e s

The reference numeral 1 designates the chair to one rocker of which a standard 2' is secured that is formed with an elongated slot '3 and the upper end of which terminates in a head 4 in which a curved slot 5' is formed. A set screw. 6 extends through the slotted portion 3 of' the standard 2 and serves as a guide for said standard, said screw being carried by'a bracket 7 carried by thechair. To this standard 2 adjacent the head 4 an arm 8 is bolted as at 9 and .said arm is provided with a pin 10 that rides in the slotted portion 5 of the head 4;

housing being bolted'together as at 13. A

fan shaft 14 journaled in the sides of the housing carries a rotary fan 15 and'said; shaft is further provided with a cog wheel stesfitatan triaersratent: fratented Mar. 7, 1916'; Application filed irahuary s, 1915., Serial no; 1,130. r I I g 16 inmesh. with a gear wheel; 17 carried PET R; M RTIn upon shaft- 18 also j ournaled in *the housing and said Sh e 1591 further provided with a eog r 1wheel 19 mesh with gear wheel 20 carriedqby 521 also 1' ournaled in the housing; Af-lever 22 is loose upon shaft 21-" and- springs-23'} disposed upon said shaft has one end secured to the side of the housring and the other to the lever- 22-1 In the flf-I'EBxzllGIll'llIlfltlOIl of the lever 22 a pin 24 is carried and upon the same a casting 25 is loosely carried, said casting carrying a weight26 and a pawl 27 adapted for' engagement with the teeth of the gear Wheel 20. A- rod 28 connects the pin 24 with a lever 29 pivoted at 30 to the standard 2 and the opposite end of'said lever is 'pivotally connected; to a rod 31, which'extends through a bearing 32 connected to the standard 2,

rockers the standard2 is-drawn toward the floor causing the bearing 32 to ride downesqf that carries a roller" 33 that rests upon the floor. g v

As the chair moves backward upon its ward over the rod 31 and causing the con:

nections of that rod to pull downwardupon the pin 24 thus causing thepawl 27 to rotate the gear wheel 20 and shaft 21 and gear 20 in mesh with cog wheel 19will rotate shaft '18 and gear wheel 17 which'throug'h its connection with cog wheel 16 will romotion. The upward: movement of the [rocker will reverse this movement andthe spring 23 will raise the pawl out of engagement with the wheel '20 and move it back i into position forthe next downward movement ofsaid rocker.

" What is claimed is a 1 5 y 1. In a fan attachment for a rocking chair,

a slotted standard secured .to .1 one chair rocker and terminating at its free extremity 1 in a head formed with acurved'slot, a guide for said standard disposed in the slotted portion thereof and carried bysaid chair,

'tate the fan shaft 14 thus setting the'fan in v an arm terminally secured to said standard and slidably associatedwith the slottedportion of the head thereof, a housing carried by said arm, shafted'jfan carried by'said housing, gearlng disposed in i'said housing and operatively associated withs'aidfa'n, a

lever loose upon one of the shafts of said gearing, connection between said lever and gearing whereby movement of the former in one direction-willflimpart motion" to the latter, a spring connecting said lever and the housing where y the former may be returned to initial position after eachengagement with said gearing, a rod operatively associated with said standard and having a roller'bearing on the fioor and connection betweensaid lever and rod whereby movement will be imparted to the former as the chair and standard are moved in one direction.

2. In a fan attachment for a rocking chair, a housing open at one end, movable supporting means for said housing carried by said chair, a shafted fancarried by said housing, gearing carried by said housing and operatively associated With said fan, a lever loose upon one of the shafts of said gearing, means carried by said lever for engagecopies of this patent may be obtained for five cents each, by addressing the ment with said gearing to impart motion to the same as said lever is moved in one direction, a lever pivoted to said housing supporting means, a rod pivoted to said lever and having a roller bearing on the floor and connection between said lever and the first named lever whereby movement is imparted to the latter member through movement of the chair.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two subscribing witnesses.
